I was recently reading something about power scaling, a patent designed by Kevin O'Conner of London Power (www.londonpower.com). I could see something like that being usefull in Plexi type or single channel amps that generally derive there overdrive through the output tubes as apposed to preamp tubes. I talked to Kevin over the phone about this. it allows you to dial in the amount of wattage output preserving both tube life and speakers as apposed to using a power attenuator which does nothing to preserve tubes. Technically i have no idea how exactly this works though.
Just wanted to know if anyone has tried this mod out on any amps at all and how it sounds? I know Stephenson Amps uses this patent in the manufacture of his amps but i have not yet heard one.
BTW for those of you more technical minded folks, look up his books The Ultimate Tone, tons of very informative info about amp design and mods. I did get the first two books of that series. Slowly learning some stuff about amps, although a tech im deffinatly not. I only understand the theory of the way amps work with very limited technical knowledge. His books get right into details on resistors, caps, tranny's etc. and there layout with tons of possabilities. Its a good read.
Anyway getting back to Power scaling. If any have tried the mod, how does it sound?
